Is there a new rule coming that would prevent people from extending H1B status beyond 6 years?
There is no indication of such a rule being proposed at this time. Further, the ability to extend H1B status beyond 6 years is partially based on a law, rather than a regulation. Therefore, to get rid of this rule would likely require that Congress intervene. (18.Dec.2017)
I read that section of AC 21 law and it specifically states that the attorney general may grant 3 year extensions after 6th year for people with approved i140. They can choose to follow this if they want.
There is another section that says the attorney general shall grant one year extension based on approved i140 which mandates them to grant one year extensions. But extension every single year would be pain in the ass for employers and it could be prohibitive to hire visa people. It's a pain for people too as there would be a pending petition a given point unless they wish to spend $1225 for every premium application. It'll also mandate stamping with every travel and would also hinder free travel during pending petitions.
